140	  talk to these devices using the SCSI protocol:
141

143	  writer software look at Cdrtools
144	  (<http://cdrtools.sourceforge.net/>)

209	  of SCSI related problems.
210
211	  If you say Y here, no logging output will appear by default, but you
212	  can enable logging by saying Y to "/proc file system support" and
213	  "Sysctl support" below and executing the command
214
215	  echo <bitmask> > /proc/sys/dev/scsi/logging_level
216
217	  where <bitmask> is a four byte value representing the logging type
218	  and logging level for each type of logging selected.
219
220	  There are a number of logging types and you can find them in the
221	  source at <file:drivers/scsi/scsi_logging.h>. The logging levels
222	  are also described in that file and they determine the verbosity of
223	  the logging for each logging type.
224
225	  If you say N here, it may be harder to track down some types of SCSI
226	  problems. If you say Y here your kernel will be somewhat larger, but
227	  there should be no noticeable performance impact as long as you have
228	  logging turned off.

1012	  "Tagged command queuing" is a feature of SCSI-2 which improves
1013	  performance: the host adapter can send several SCSI commands to a
1014	  device's queue even if previous commands haven't finished yet.
1015	  Because the device is intelligent, it can optimize its operations
1016	  (like head positioning) based on its own request queue. Some SCSI
1017	  devices don't implement this properly; if you want to disable this
1018	  feature, enter 0 or 1 here (it doesn't matter which).
1019
1020	  The default value is 8 and should be supported by most hard disks.
1021	  This value can be overridden from the boot command line using the
1022	  'tags' option as follows (example):
1023	  'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to

1025	  and set queue depth to 10 for target 0 / lun 2 on controller 1.
1026
1027	  The normal answer therefore is to go with the default 8 and to use

1045	  you are using very large hard disks with large cache (>= 1 MB) that
1046	  are able to take advantage of more than 32 tagged commands.
1047

1053	default "20"
1054	help
1055	  The SCSI Parallel Interface-2 Standard defines 5 classes of transfer
1056	  rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80.  The numbers
1057	  are respectively the maximum data transfer rates in mega-transfers
1058	  per second for each class.  For example, a FAST-20 Wide 16 device is
1059	  able to transfer data at 20 million 16 bit packets per second for a
1060	  total rate of 40 MB/s.
1061
1062	  You may specify 0 if you want to only use asynchronous data
1063	  transfers. This is the safest and slowest option. Otherwise, specify
1064	  a value between 5 and 80, depending on the capability of your SCSI
1065	  controller.  The higher the number, the faster the data transfer.
1066	  Note that 80 should normally be ok since the driver decreases the
1067	  value automatically according to the controller's capabilities.
1068
1069	  Your answer to this question is ignored for controllers with NVRAM,
1070	  since the driver will get this information from the user set-up.  It
1071	  also can be overridden using a boot setup option, as follows
1072	  (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
1073	  for FAST-20 synchronous data transfer (20 mega-transfers per
1074	  second).
1075
1076	  The normal answer therefore is not to go with the default but to
1077	  select the maximum value 80 allowing the driver to use the maximum
1078	  value supported by each controller. If this causes problems with
1079	  your SCSI devices, you should come back and decrease the value.
1080
1081	  There is no safe option other than using good cabling, right
1082	  terminations and SCSI conformant devices.
